mydupefinder

A command-line tool to detect and optionally remove duplicate files based on their hash values (MD5 or SHA-256). This tool uses the Crypto++ library for hashing and the C++17 filesystem library for directory traversal.

Features

• MD5 or SHA-256: Choose your hashing algorithm via command-line flags (-md5 or -sha256).
• Recursive Directory Scan: Traverses all files in the specified directory or directories.
• Dummy Test Mode: Optionally perform a dummy test run without actually deleting any files.
• Manual or Automatic Deletion: Choose whether to keep one file and delete the rest automatically, or manually pick the file you want to keep.
• Logging: Generates a timestamped log file detailing all actions taken.

Installation in a linux Shell

1. Clone this repository: git clone https://github.com//mydupefinder.git
2. cd mydupefinder
3. g++ -std=c++17 -O2 mydupefinder.cpp -o mydupefinder -lcryptopp

Usage ./mydupefinder [options] [ ...]

Options -md5

Use MD5 hashing algorithm. -sha256

Use SHA-256 hashing algorithm (default). -help or --help

Display usage information. Example

Scan a single directory using SHA-256 (default):

./mydupefinder /path/to/directory

Scan multiple directories using MD5:

./mydupefinder -md5 /path/to/dir1 /path/to/dir2 /path/to/dir3

Show help:

./mydupefinder -help After running the tool, you will be prompted to select directories from which duplicates should be removed, choose whether to perform a dummy test, and optionally confirm manual deletions. A log file named log_YYYYMMDDHHMMSS.txt will be created in the current working directory with details of the actions taken.
